Has any one tried flashing a p4p800 with p4p800 se or vm bios i have my ct-479 , 1.6ghz 2mb dothan and a p4p800 just waiting to run.
Try it and you will be first to know :) You got some other board you can hotflash with?
not another asus board just a abit ic7-max3.
I am tempted to try but it's a good board and dont want to trash it. I had my p4 2.8c up to 3.7 stable 265 fsb on it so i have high hopes for running the dothan on it with a cascade(cathar) water cooler on it.
Well, you can probably hotflash with the MAX3 board, it uses awd right?
I just found a hotflash guide explaining how to remove the bios from a good board / insert the duff bios and re-flash it so i will give this a go later on just need to find my bios remover first.
asus have a download section for the ct-479
ct-479 downloads
the max3 uses pheonix award bios just like the msi nforce2 i have.
Will check the 2 shuttle sff systems i have too
i just booted the p4p800 and it's using ami bios.
i tested the p4p800-vm bios 1009 first and afudos says the rom has an invalid romid is is incompatible with this board. :(
I guess if you new how you could get the rom id from a p4p800 bios and update the p4p800-vm bios :confused:
no need for that if you run /n /pbnc after the file name it will force the update which i just did and i am about to restart the p4p800 (deep breath)
hits reset
it booted ok with the p4p800vm logo but it gave a pci irq error.
I can get into the bios and everything looks ok.
i will do some testing and get back.
I had flashed from a bios that predated the CT-479 support with a CT-479 in use. In the BIOS it just showed my CPU as being a "Genuine Intel". This was on a P4P800-SE and the bios was dated late '04. Just thought I'd throw that out if anyone wanted to know.
I have windows xp installed no problem. The only thing that wont work is the 3com lan as the p4p800-vm uses an intel lan.
Just need to get the ct-479 installed and upgrade the bios.
this p4p800-vm has no overclocking options at all I hope the new bios for the ct-479 is better.Has anyone run a actual p4p800-vm with the ct-479 ? I might have to try the p4p800-se bios see what that does.
P4GD1 now officially supports the P-M adapter
http://xtremesystems.org/forums/show...648#post842648
Nice to hear, ordered the Asus P4GD1 on Friday. Gonna use the adapter and a Celeron M 1,3 GHz 1 MB. My first new Intel system i 7 years. Back then i had a Pentium II 300 on an Asus P2L97. :toast:Quote:

When I got to 1.55Vcore, something died. I haven't tested everything yet but I'm pretty sure it's the CT-479. Even though I couldn't get the cpu past 2.25, it did that speed at 1.25 volts / stock cooling. I wish you better luck than I Kamerat....Quote:

I'm not as good at board level work as I'd like to be, but I think the problem is inherent in the fact that while the CT-479 is receiving external power via a molex connector, the socket is still recieving power from the motherboard.
So far, everyone who's had problems with this adapter came out of it with a processor that survived.
If the voltage regulation on the motherboard and processor have no scope of the voltage regulation on the CT-479 adapter(and vice versa), it might be leading to more power being drawn than neccessary.
Try unplugging the 4-pin molex connector on the motherboard (the one that's proprietary for Pentium 4 boards).
If it boots, then it'll prove my theory. If it doesn't, then it's probably due to inferior components on the CT-479.
Wht hard modd ? putting a small wire across 2 points of the socket so the board thinks the cpu has a greater vcore range or is there another way on the ct-479.
Not had time to connect the ct-479 but will tomorrow but i do have clockgen and eist to make changes with out the bios.

It requires that a bios be modified to support the Pentium M.Quote:

Give me a model number and I'll see if it's possible for that board.
Yes the hard modd is the wire between 2 pin of the socket :D
like abit ic7 for example..Quote:

besides helping to recognize correct name and some minor microcode update to cpu itself..
the only thing incompatible would be maybe vid-pins..
like you put a mobile celeron onto abit i*7 and mobo only gives it 0.7-0.8v by default...

The point of the adapter is to rewire the socket to support the Pentium M.Quote:

Ok, I have a strange problem, using the 1009.001 beta bios for a while and I can't set my VCORE below 1.500V. It always defaults to 1.56V in the BIOS. I used to have the full range of options, however suddendly all but 9 of them disappeared :confused: and I can only select between 1.500 - 1.600V. Now this isn't much of a problem with my Celeron M 340 (Banias core) but it's a problem for my C-M 350 (Dothan core). When I plugged it in I thought maybe it'd redetect the proper VCORE but no, 1.56V! This thing is supposed to run like 1.26V or so. I can lower it to 1.5V but that's still too much for comfort. Flashing back to the official latest BIOS didn't help at all with any CPU (P4C, C-M 340, C-M 350).
Anyone have a simular problem with VCORE settings?
No, I didn't try that,...but I will when I figure what died and order a replacement. Just a bump in the road.Quote:

Pentium M 755 for £70 new (Ebay can be good some times :) ! )
Asus P4P800se for £45 almost new
Asus CT-479 for £30 new
I know the 755 is only 400Mhz Fsb but as it has a 20x multiplyier (i think) i have high hopes - now i have some questions (apologies if there dumb ones)
1. Whats the best memory for this system, can I go for 2 gigs of bog standard PC3200 or do I need some better memory - OCZ, Corsair etc at Higher raitings - Im confused about all there memory bus to Processor bus speeds it seems like most people have the memory bus at greater then the Processor Bus surely this makes it no faster ?
2. It seems that 400mhz Dothans dont overclock so good, what do you think i can expect as my maximum stable overclock - basicaly what should i aim for, I also found that there is a way to convert a 400Mhz dothan to a 533Mhz dothan by grounding the bsel0 pin apparently (http://www.hardforum.com/showthread.php?t=888963) unfortunatley the database seems to be down :(
Sorry again for the newbie questions ;)
Thanks in advance for any input!
Stu
Well actually the items are on the way to be precise !
Stu
It always give you a performance boost if you got better memories Stu!
I have 735 1.7GHz 400MHz dottie which does ~2.7GHz stable wit 1,49Vcore and air on Aopen 855GME-board. So not much difference there. According to many experiences 533 chips front side bus can very propably be overclocked considerably higher(over 200MHz) than 400 chips(under 190).
This creates a problem because you only have 1:1 or 2:3 memory dividers available on P4P or P4C -boards when fsb is set under 200MHz(this is prolly the same on P4GD1 -board). I would want to have at least 3:4 memory divider just like with 855GME-boards.
Wow luseruser :-o was that using ct-479 and what mobo are you using
I have a stick of OCZ gold EL 3700 so ill try that first see how it gos
Thanks for the info
I have the CT-479 running in the p4p800 with p4p800-vm bios v1016.
Still have the problems with no lan and it wont startup after you shut down unless you remove the power but it did the same with a p4.
In the bios it shows the cpu as unlocked and the bios give multipliers from 8 up to 24 but No fsb or core volts options.
:banana: :banana:
No CT-479 ... i´m using that good ole Aopen Lfs855GME -board 24/7, multiplier 16X, FSB 169, KHX BH-5 memories(256MB stick and 512MB stick) with 3:4 memory divider 2-2-2-5, @225MHz.Quote:

yes it wont allow multipliers over 16.
I currently have it set at 13x157.5 fsb 210 for the ram but at 2.5-3-3-6 as i cant run any higher than 2.65v at the moment
so the 1.6ghz is running at 2047ghz stock voltage.
1m super pie droped from 49s to 35s which is 4 seconds faster that my p4 2.8c runnigs at 3.7
I have found a problem with pci cards not working i could be just the lan cards as that is all i tested so far due to the on board not disabled as it should be the intel not 3com.
just have to hope asus do a good job of the p4p800 bios and quick.
I have a ocz ddr booster in the way for my other pc so i can give it a go in this one It has 2x xms 3500 v1.1 bh-5 chips in crying for some volts.
edit: just ran at 15x 153fsb ram at 210 2-3-3-7 for a time of 33s stock volts.
So it seems that on old p4p800 board you get to use that 3:4 memory divider... hmm intresting. Couple of reviews and user experiences have been that on P4P800 SE you don´t get to use that divider when fsb is under 200.
Can you lock the pci/agp to 33/66 on that board?
stock settings with the p4p800-vm bios 1016 in the p4p800
cpu fsb 100
ram 133
agp 66 locked
pci 33 locked
at 533 fsb it might show more memory options this is common with asus boards.
Yes, going to 133 mhz FSB in BIOS will give you 1:1 or 4:5 dividers.Quote:

this wont matter at the moment anyway as i tried the p4p800 se bios in the p4p800 and now it wont post at all. :(
will have to hotflash it back to a p4p800-vm.
edit:
both my ic7-max3 and msi nforce2 boards wont hotflash the p4p800 bios chip. :(
awdflash gives checksum errors in the bios file and afudos says something about asf signiture missings. so unless i can find a way to overide i am stuffed and will have to look at a 2nd hand p4p800-vm board i found.
You could try Uniflash.
http://www.uniflash.org/
Yes i have that but i gave errors when programming the p4p bios in a nforce2.
will try it in a max3 now it's running again after my 6600gt just stopped working i have a ti4200 in it's place.
i must be on a run of bad luck.
on a good note the ddr booster arived today and i just orderd a p4p800-vm for £30 2nd hand.
edit: the max 3 gave the same errors when programming the p4pbios it's possible i have damged bios chip will have to wait for the p4p-vm to turn up.
Im thinking about a mobos. Which is the best? Now new supported P4GD1 ?
has anyone tried the adaptor out on the Albatron 915/478 board ??
this one: http://www.albatron.com.tw/english/i...asp?pro_id=147
its the Albatron PX915G4-Pro
Hi,
I got a question. A friend of mine has a 1,3 Dothan (Engineering sample) and he wonders if it will work on the adapter. He's worried because the adapter only supports cpu's +1,5 GHz.
The p4p800-vm arrived so i flashed the p4p800 bios back to normal and all is good.
I changed the fsb jumper on the ct-479 to 533 and lowerd the multi to 12 and now have the ram options of 266 and 333 so i can carry on testing.
Just a note that the p4p800vm + ct-479 + ocz ddr booster over 2.8v= Death to the mobo :( hope thats the 3rd time i am unlucky.
see post 108 for u wire mod on ct-479 worked for me i get 1.5 vcore.
http://www.forumdeluxx.de/forum/show...=112010&page=5
Works nicely w/ 1.3G celeron-dothan so I dont see why it wouldn't w/ 1.3G dothan.Quote:

Has any one here with a P4P800-SE (or other P4C) had VCORE issues? My dothan Celeron M 350 (1.3Ghz) defaults to 1.568V with both the official and beta BIOS. I have to use the beta BIOS so I can "undervolt" it, however I can only drop it to 1.5V in the BIOS. Still it doesn't give me anywhere near default VCORE.
Actually the same happens with a C-M 340, detects 1.568V default. I think the real default is 1.356V. It looks the the board is completely ignoring the VID request. :confused:
any info how the 1M celeron overclocks with adapter?Quote:

i'm interested of cm 360J, i just hope that the perfomance penalty aint too big..
and damn verkkokauppa.com increased ct-479 proce from 33€ to 50 € :mad:
that's excatly what I want to know too =)Quote:

I've only had the time to do a very quick OC test with the 1.3G Celery and it would run SPI1M at 2.12G all stock (def. voltage 1.24V - 2M dothan have a def. Vcore of 1.324V). The time was around 37.1 so not much slower than the 2M version. But obviously more benchmarks need to be run in order to see what the real performance difference between the 1M and 2M versions of the Dothan are.
in case you need an adapter => bunch of adapters in stock here
does the adaptor works with the p4c800 non E-DLX?
yes it does BUT it requires useing P4C800-E BIOS (or some other special modded BIOS).Quote:
does the adaptor works with the p4c800 non E-DLX?
So before you put the Dothan and the adapter in make sure the board is running with the latest P4C800-E BIOS.
Does flashing a P4C800-E Bios in a P4C800-DLX (not E) work? Has it been done before? Is there a modded p4c800 bios that works?
uhm check the post right above yours? :stick:
if it works for the p4c800 I see no reason why it wouldn't work for the p4c800 dlx...
lol I read it but i'm afriad that flashing my p4c800 with a different BIOS may screw it up so I want to be sure that it works.Quote:

ok thanks I think i will buy the adapter and flash my p4c800 deluxe. I have one more question...since I just have the board but no s478 cpu is it possible to flash it without the cpu?
Unfortunately, no, you can't.Quote:

I would not recommend getting unless you're already on a fairly dated Socket 478 system and just want a cheap upgrade... or if you're trying to build a silent and cool MediaPC.
Do you think they will release a BOIS for the P4S800-E D motherboard. With my Mach1, I would love t freeze it to see what it could reaaly do!
Any experience with Asus P4G1 ?
Works with this mobo pci/agp lock ?

How did you mount your vapochill to the cpu? Could you please post some pictures? (i think it is possible with the old S478 kit, but didn't think it was possible with the new S478, S754, S939, S940 kit which is what the XE2 comes with i think).
It's not hard to make a custom mounting plate.
I think the problem is that the CT-479 covers 2 of the motherboard mounting holes.
See in this picture: http://www.gamepc.com/images/labs/re...t479sockLG.jpg
That is why i think the old S478 vapochill kit will work as it uses the existing mounting bracket, but the new kit uses the motherboard holes.
You can still use the mounting holes, it just takes a little ingenuity:

the cpu will come sunday and i will tell you evry think..
i have the kit of xe and the kit of xe 2 here!
no bady tell me if i need to do some mods to my mobo or to the ct 479!
to get the best fsb/over clock with this cpu!
for now i do only the droop mod for the mobo did i need to do mor mods? if yes pleas tell me which mods

guys ?
